QNAP TS-251B-2G 2-bay NAS Review

To test real life file/folder performance we use a number of different file/folder combinations to test the read and write performance of the NAS device. Using the FastCopy utility to get a MB/s and time taken for each transfer, the data is written from and read back to a 240GB SSD.

We test using the following file/folder combinations:

100GB data file.

60GB ISO image.

60GB Steam folder: 29,521 files.

50GB Files folder: 28,523 files.

12GB Movie folder: 24 files – mix of Blu-ray and 4K files.

10GB Photo folder: 621 files – mix of .png, .raw and .jpeg images.

10GB Audio folder: 1,483 files – mix of .mp3 and .flac files.

5GB (1.5m pixel) image.

BluRay Movie.
